FUEL-MIXING DEVICE.

Application filed January 9, 1922.

T0 aZZ whom it may concern:

Be it known that I, GEORGE M. HART, a citizen of the United States: anda resident of Des Moines, in the county of Polk and State of Iowa, haveinvented a certain new and useful F uel-Mixing Device, of which thefollowing is a specification.

The object of my invention is to provide a fuel mixing device adapted tobe interposed in the path of travel of the fuel mixture from thecarburetor to the engine, the attachment being of simple, durable andcomparatively inexpensive construction.

More particularly, my invention relates to an attachment arranged to beinterposed between a carburetor and an intake manifold in the path oftravel of the fuel mixture and provided with a fan blade member capableof rotary movement for thoroughly mixing and breaking up any of theparticles of gases or fuel which have not been thoroughly vaporized.

Still another object is to provide a funnel shaped passage way, in myattachment for tending to direct the flow of fuel mixture towards thecenter of the passage way of the intake manifold, and keep it away fromthe walls thereof.

Still another object is to provide a cone shaped screen member on oneside of the attachment, so that the fuel mixture must pass therethrough.Still another object is to provide a web for forming a bearing memberfor a fan blade, which is operated, due to the suction, from the intakemanifold.

The funnel shaped passage way of my clevice, is particularly designed tocarry the heavier particles of gases, which ordinarily cling to thewalls of the manifold towards the center and towards the fan blade, sothat the revolving fan blade will thoroughly mix the fuel.

Figure 1 is a side elevation of an intake manifold and carburetor, withmy improved attachment, installed therebetween.

Figure 2 is a sectional view taken on line 2-2, Figure 1, a part of thescreen being broken away to better illustrate the construction; and

Figure 3 is a sectional view taken on lines 3-3 of Figure 2.

In the accompanying drawings, I have used the reference numeral 10 toindicate generally a carburetor of ordinary construction, which isprovided with a flange 11, at

Serial No. 527,936.

its discharge end. An intake manifold 12 of the ordinary construction,is provided, which has a flange 13 formed on its receiving end.

The flange 13 is substantially the same size and shape as" the flange11, and is designed to normally rest against the flange 11. Each of theflanges 11 and 13 are provided with a pair of openings (not shown),through which are extended the bolts 11, which securely hold thecarburetor 10 to the intake manifold 12.

My attachment is substantially the outline-of the flanges 11 and 13, andconsists of a thin plate 15. The plate 15 is designed to be receivedbetween the flanges 11 and 13. The plate 15 is provided with a pair ofopenings 16, which register with the open ings in the flanges 11 and 13,so that the bolts 14 may be extended therethrough for securely holdingthe plate 15 between the carburetor and manifold. Resting against eachof the sides of the plate 15, are gaskets 17. The gaskets 17 are placedbetween the flanges 11 and 13, for forming a tight joint between theparts.

The plate 15 is provided with an enlarged opening or passage way 18. Theopening 18 is in alignment with the discharge opening of the carburetor10, and with the receiving opening in the intake manifold 12.

Extending across the opening 18, and formed integral with the plate 15,is the web or spider 19 and has fastened to it a sleeve 20. The web 19is provided with an opening 21, registering with the opening in thesleeve 20.

It will be seen that the web 19 provides a bearing member, the purposeof which will be hereafter more fully set forth.

The edge of the opening 18, between the web 19, is formed with aninwardly extending flange 22. The flange 22 is inclined, so as to formsubstantially, a funnel shaped passage way through the attachment.

Received within the sleeve 20, and extending through the opening 21, isa spindle The spindle 23 may be a bolt if desired. In my drawings 1 haveshown the spindle with a screw threaded end 24, having a nut 25 thereon.One end of the spindle 23 is provided with a head 26.

Received between the head 26 and the sleeve 20, and on the spindle 23,is a fan blade 27. The fan blade 27 is capable of rotary movement on thespindle 23.

' ing of the fuel through the revoli'in Fastened to one side of theplate 15 is a screen 28, of comparatively heavy inesh. On the oppositeside ot the plate a cone shaped screen member 539 is provided. The endof the screen member 29 is provided with a series of openings so as toprevent any possible collecting of gases within the screen member 29.

The screen member 29 completely encloses the tan blade 2?. The coneshaped screen member 29 extends into the receiving end of the intakemanifold 12.

The gases from the carburetor will first pass through the screen 28, anddue to the flanges 22, will be directed towards a conr mon center, andbrought into the passage where the tan blade 2 operated.

The suction "from the engine or vacuum, which draws the tluel into theengine will cause the fan blade 27 to re' .*olve. The pass an blade 2'7will cause it to be tlita-oa rhl up, and any particles o't to be.

thoroughly vaporized. The see. after passing; through the an blad willthen pass through the fine mesh screen into the intake manifold.

It will be seen that I have provided a device, which causes the ituel orgases to be passed through a revolvingtan, wl will be tnoroug'hlyhrolren up and ;hence, permitted to pass into the inalce maniliold. I Inthe form of device shown. l form the plate 15, the flange 2-2 and theweb 19 oi a single piece of material, by die stamping.

My attachment can readily and easily be secured to any carburetor, andis very eriicient. My device will to a great extent prevent carbon fromforming in the engine, and the power obtained from the engine will beincreased, due to the fact that all the gases are utilized to thefullest extent.

some changes may be made in the construction and arrangement of thevarious parts of my device, without departing from the essentizlfeatures and purposes of my invention, and it is my intention to coverby my claim, any modified forms of structure or use of mechanicalequivalents, which may be reasonably included within its scope.

l claim as my invention:

A fuel n'iixingg device comprising a plate adapted to be interposedbetween a carburetor and the intake manifold of an engine, said platehaving a pair of openings there in for attaching it in position andhaving an enlarged opening adapted to register with the op nings in thecarburetor and the intal-re manifold, an inwardly inclined flange formedon the edge of said last openin said ll oer designed to project intosaid intan: told a cone shaped screen secur d and received between saidscreens. and revoluble by the suction for intake manifold,

whereby l ull mixture will be drawn through the fan blade causing; it torevolve and be broken up as stated.
